4x2 HDMI Matrix Switch

This LUOM matrix switch routes four HDMI sources to two displays independently. It supports 4K at 60 Hz with 18 Gbps bandwidth and HDCP 2.2 compliance. The unit includes an IR remote and front-panel buttons for source selection. Ideal for home theatre, office or classroom installations needing flexible multi-screen routing.

Check HDMI 2.0 and ARC compatibility

Verify that each source and display works with HDMI 2.0 and HDCP 2.2 for 4K 60 Hz signals. Confirm your sound system and TV both support ARC if you plan to use the return channel between Input 4 and Output 1. Ensure you have four HDMI cables for inputs, two for outputs and an optical or 3.5 mm cable for extracted audio. The included power adapter must be connected for operation.

Replaces basic splitters or manual switch boxes

Unlike a simple splitter this matrix lets each output show a different source simultaneously. The built-in scaler automatically downscales 4K to 1080p for older screens without manual setup. The jump is worth it when you need independent dual-display routing, ARC audio return or lossless formats such as DTS HD and Dolby TrueHD. Buyers who only need one source duplicated to two screens do not need this matrix.

Questions about this item

What cables and accessories come with the LUOM 4x2 HDMI matrix, and what must I provide myself?

The box includes the OZJ2-1 matrix switch, a power adapter, an IR remote and a user manual. You must supply four HDMI source cables and two HDMI display cables, plus an optical or 3.5 mm audio cable if you want extracted sound.

Which video specification should I match when choosing sources and displays for this matrix?

Pick sources and displays that support HDMI 2.0 and HDCP 2.2 so they can handle the matrix’s 4K 60 Hz 18 Gbps capability; the unit will automatically downscale 4K to 1080p only when a connected display cannot accept 4K.

How does the 18 Gbps bandwidth translate to real-world use with my 4K 60 Hz gear?

The 18 Gbps path carries full 4K 60 Hz 8/10/12-bit colour and lossless formats such as DTS-HD and Dolby TrueHD without compression, giving smooth gaming and cinema playback on both outputs simultaneously.
